DESCRIPTION
The DS*8B*0 Digital Thermometer provides 9 to **-bit (configurable) temperature readings which
indicate the temperature of the device.
Information is sent to/from the DS*8B*0 over a *-Wire interface, so that only one wire (and ground)
needs to be connected from a central microprocessor to aDS*8B*0. Power for reading, writing, and
performing temperature conversions can be derived from the data line itself with no need for an external
power source.
Because each DS*8B*0 contains a unique silicon serial number, multiple DS*8B*0s can exist on the
same *-Wire bus. This allows for placing temperature sensors in many different places. Applications
where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings,
equipment or machinery, and process monitoring and control.
